FWIW (not much) I once installed an external feed for the same reason. The
previous owner had run it that way for perhaps 10,000 miles before I got it, but
it was already in the car before I noticed the problem. Why are these pushrods
rusty ???
After installing the oil feed, and even adding some restriction to the line, I
literally got a warning from the California Air Resources Board for excessive
smoke !
Adding some valve stem seals solved the problem for awhile ... but eventually
one of them became dislodged and cost me a piston. (Oil has an extremely low
octane, but I apparently couldn't hear only one cylinder knock over the general
mechanical racket of a tired engine). So, I ran a long drill bit down through
the block (with the cylinder head off) and drilled through the bearing insert !
I definitely do NOT recommend this to others, but it worked for a long time for
me. Somehow that old short block (by now with a rebuilt head & rocker shaft,
plus used liners & pistons, new bearings, etc.) just kept running ... it's
sitting in my driveway today.
